RIM.

Application filed July 9, 1923. Serial No. 659,329.

1 '0 all whom it may concern Be it known that we, GEORGE S. GREENE and LORENZ l i mrrnn, citizens of the United States, both residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Rims, of which the following is a full, clear, and exact description, such as will enable other skilled in the art to which it'appertains to make and use the same.

This invention relates to an improvement in rims and with respect to its more specific features to demountable or rims.

An object of the invention is to provide a rim or" the class described, which may be quickly and easily assembled or disa. sembled 1 Another objectis to provide a rim which may be assembled inthe tire and afterwards placed upon the wheel.

Another object is to provide a construction of sectional rim such that the normalusage of the wheel tends to tighten the sections of the rim with respect to each other.

Another object is to provide a two-part rim, wherein one of the parts is sectional and clamped between the other part and the tire.

Another object is to provide a two-part rim having one part sectional, wherein the pressure of the seated tire is utilized to clamp the parts together. Y

Other objects of the invention will be in part obvious and in part pointed out hereinafter. v

The invention accordingly comprises the -features of construction, combinations of elements, and arrangement oi parts, which will be exemplified in the construetiens hereinafter set forth and the scope oi" the HPPllCHtiOll of which will be indicated in the claim.

For a fuller understanding of the nature and objects of the lHL'QIItiOD reference should be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure 1 is an edge view oi the improved rim with the sections of the outer part separated,

Fig.

is a plan w with th Parts s arated,

removable supporting the same.

Fig. 3 is a radial section of the rim.

In the present embodiment of the invention the improved rim is con'iposed of two main parts,.,an inner rim, or rim part 1 which is'annular, and an outer rim or rim part to be described, which is also annular in form when assembled, but; is divided transversely into a plurality of arcuate rinr The part 1 1s provided at one sections. side edge with a marginal. flange 2,which is adapted to engage and support one side of the tire. The outerrim part as mentioned is divided transversely into a plurality of similar'arcuate rim sections 3 formed on an are having the same radius as that of the rim part 1,a nd of such a length that when fitted in abutting relation with each otheron-the outside of the rim part 1, they will lie circumferentially relative to each other on said rim part1 to form acomplete substantially circular rim 'part. In the modification shown, there are three of these rim sections 3 which are hereinafter referred to as circumferential sections. As shown in Fig. 3, each of the" circumferential sections is provided with an outwardly extending marginal flange d for contacting with the outer side of the tire and with an inwardly extending flange underlying and bearing against the inner surface otthe' surrounding tire for 3' is provided at one edge with a flange 4t, and when the sections are assembled out side of the part 1, the flanges 4 will be sul stantially continuous, and will afford a support for the opposite side of the tire from the flange 2. I

The parts are held together by the inflated tire and by lugs 5 on the sections 3, which engage openings 6 in the part 1. Two lugs 5 are preferably provided for each section, one of the lugs being located near each end of the section, and referring to Fig. 3, it will be seen that each lug has the face remote from the flange beveled or in clined, so that it will ride up over the part 2, and engage within the opening 6. The lugs 5 may be disengaged from'the openings 6, by spreading the sections 3. Any suitable tool may be used for this purpose as for instance a screw driver which may be inserted between the parts 2 and 3, adjacent to a lug 5. When the parts are sufiiciently separated to disengage the lug, the section f the part 3 may he slipped far enough to Each of the sections l the end of the screwdriver, to

cause the lug to rest upon the outer face of the part 1, until the remaining lug is disengaged, should there be more than one lug to the section. In order to facilitate the disengagement oil? the parts, each section is provided adjacent to each lug 5 with a. notch or curt 7, which is adapted to receive provide a purchase or fulcrum. 1 a

In assembling the improved rim the sections 3 are laid upon the 'ground'in an approximate circle with the flanges & down. The deflated pi-ieumatic tire S is dropped over the sections, so as to rest on one side thereof upon the flanges; T he part 1 is now pushed into the tire, between the sections 8,

and it is pushed clownuntil the lugs 5 e11- gage theopenings 6; hen now the tire is intlatechthe sections 3 of the outer part otthe rim are clamped tightly between the tire and the part I, so that there is no possibility oi? accidental displacen' ent, so

long as the tire inflated. Suitable'opeir Lugs may be provided in the part '1, and

in a section or sections of the outer part for the passage of the inflating valve for the tire, the said openings being indicated at 9 and 10 respectively. The latter opening is a slot extending from the unflanged edge of the part 1, to facilitate the assembling of the rim and tire. It will thus be seen that the openings 9 and d0 cooperate to circumterentially position the rim "parts to bring the respective lugs 5 andrecesses '6 into proper position for registering. 'The inner rim 1, may or may not be a permanent intended that all matter contained in the above description or shown in the accom panymg drawing shall be interpreted as illustrative and not in a limiting sense. The invention theretore is to be understood as tall fairly Within the spirit andscopc of the appended claim.

Having described our invention, What We claim as new and desire to secure by Letters Patent, is:

lnawdcvice of the character described, in combination, a tire supportmg rim part including a plurality of circumferential sections adapted to abut end to end to form a a complete outer rim part, said circumferen-y tial sections having inwardly extending circun'iterential flanges adapted to bear against the inner surface of a surrounding tire for supporting; the same, and means including a circumferential.rlm part disposed vlnslde of said circumiterential flanges, whereby inembracing such equivalent modifications as d Wardly directed radial pressure of the surrounding tire retains the rim sections in tire supporting relation with each other,

In testimony whereof Wea'HiX our signa- GEORGE: s. GREENE.
